1 Quick start guide

Complete the following steps to start the Rosemount T1056.

Prerequisites

Refer to Install for installation instructions.

The sensor cable is pre-wired to a plug that inserts into a recieving socket in the analyzer. The cable also presses through a strain relief fitting.

Procedure

1.To install the cable:

a)Remove the wrenching nut from the strain relief fitting.

b)Insert the plug through the hole in the bottom of the enclosure nearest the sensor socket. Seat the fitting in the hole.

c)Slide the wrenching nut over the plug and screw it onto the fitting.

d)Loosen the cable nut so the cable slides easily.

e)Insert the plug into the appropriate receptacle on the circuit board.

f)Adjust the cable slack in the enclosure and tighten the cable nut. For wall/ pipe mounting, be sure to leave sufficient cable in the enclosure to avoid stress on the cable and connections.

g)Plug the cable into the back of the sensor.

h)Place the sensor in either the measuring chamber or the calibration cup.

Important

The sensor must be in a dark place when power is first applied to the analyzer.

2.Make power, alarm, and output connections as shown in Wire.

3.Once connections are secured and verified, apply power to the transmitter.

When the transmitter is powered up for the first time, the Quick Start screens appear.

4.Follow the Quick Start Guide to enable live readings.

a)A blinking field shows the position of the cursor.

b)Use or to move the cursor left or right. Use or to increase or decrease the value of a digit. Use or to move the decimal point.

c)Press ENTER to store a setting. Press EXIT to leave without storing changes. Pressing EXIT also returns the display to the language selection screen.

Important

When using EPA/incandescent sensors (PN 8-0108-0002-EPA):

Rosemount T1056

Quick start guide	Reference Manual
July 2020	00809-0100-3560

•Do not power up the instrument without the sensor connected.

•Do not disconnect and reconnect a sensor while a transmitter is powered.

If this is inconvenient or cannot be avoided:

1.Cycle power to the instrument after connecting the sensor or

2.Perform a slope calibration or standard calibration routine after connecting the sensor. Following these guidelines will extend the life of the incandescent lamp and avoid premature warnings and faults due to reduced lamp life.

2 Description and specifications

•Complete system includes single or dual input analyzer, sensor(s), and debubbler assembly.(1)

•Choose US EPA Method 180.1 or ISO Method 7027 compliant sensors.

•Resolution 0.001 NTU

•Full featured analyzer with fully scalable analog outputs and fully programmable alarms with interval timers.

•Intuitive, user-friendly menu in seven languages makes setup and calibration easy.

2.1Features and applications

The Rosemount T1056 turbidmeter is intended for the determination of turbidity in water. Low stray light, high stability, efficient bubble rejection, and a display resolution of 0.001 NTU make the turbidmeter ideal for monitoring the turbidity of filtered drinking water. You can also use the turbidmeter in applications other than drinking water treatment. Examples are monitoring wastewater discharges, condensate returns, and clarifiers.

Currently, new ISO 7027 systems are available, with replacement EPA 180.1 sensors available for current install base. USEPA 180.1 sensors use a visible light source. ISO 7027 sensors use a near infrared light emitting diode (LED). For regulatory monitoring in the United States, you must use USEPA 180.1 sensors. Regulatory agencies in other countries may have different requirements.

The turbidmeter consists of a transmitter, which accepts either one or two sensors, the sensors themselves, and a debubbler/measuring chamber and cable for each sensor. The cable plugs into the sensor and the transmitter, making setup fast and easy. Sensors can be located as far as 50 ft. (15.2 m) away from the transmitter.

The turbidmeter incorporates the popular and easy to use Rosemount 1056 transmitter. Menu flows and prompts are so intuitive that you practically do not need a manual. Analog outputs are fully scalable. Alarms are fully programmable for high/low logic and dead band. To simplify programming, the transmitter automatically detects whether an EPA 180.1 or ISO 7027 sensor is being used.

The turbidmeter is available in an optional configuration in which the transmitter, sensor(s), and debubbling flow cell(s) are mounted on a single back plate. The sensor cables are pre-wired to the transmitter, so setup is exceptionally fast and easy. Simply mount the unit on a wall, bring in power and sample, and provide a drain. To order this option, consult the factory.

2.Attach a piece of ⅜-in. ID soft tubing to the drain fitting. The debubbler must drain to atmosphere.

WARNING

High pressure and temperature

Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and the process temperature is lowered to a safe level!

Reference Manual	Install
00809-0100-3560	July 2020

CAUTION

Reading errors

During operation, the debubbler is under pressure. A 0.040 in. (1 mm) orifice in the outlet provides the pressure. Back pressure helps prevent outgassing, which can lead to bubbles accumulating on the sensor face, resulting in erroneous readings.

Do not exceed 30 psig (308 kPa abs) inlet pressure.

The amount of pressure in the debubbler can be estimated from the flow rate. See

Table 3-2.

To control and monitor sample flow, a valved rotameter with fittings is available (PN 24103-00).

3.Attach the rotameter to the debubbler outlet.

You can also use the rotameter to increase back pressure on the debubbler if additional pressure is needed to prevent outgassing.
